One of the most intriguing aspects of the famed case was the common belief that prosecutors Marcia Clark and Christopher Darden were more than just colleagues. Sarah Paulson and Sterling K. Brown's chemistry-packed character portrayals of Clark and Darden, respectively, on American Crime Story have further fueled the relationship speculation.

What exactly is the truth, you ask? "Chris and I were trench mates," Clark said. "He kept me from just utter depression so many days."

Clark explained that the jury's blatant disdain for her in the courtroom and the prying eyes of the public often left her feeling "dispirited" and Darden was one of the few people who could cheer her up.

"Sometimes it would really get to me," she spilled. "And he would be there to say, 'It's alright, it's going to be okay. If we just keep putting on the evidence, they'll get it. They'll get it.'"

However, Darden's 1996 memoir, In Contempt,alludes that the courtroom duo's relationship ran deeper than just "trench mates."

"She and I were two passionate people thrown together in a trial that left us exhausted and lonely," Darden wrote. "She was willing to take off her jewelry and go to jail with me over a ridiculous contempt ruling. I was willing to be at her side during her child custody deposition."

"We sat up listening to hip-hop and R&B. We danced a few times and drank a few bottles of wine,"

Darden continued. "In my mind, that is a relationship."

At the time of the trial, Clark continually denied rumors surrounding their relationship. In fact, when People reported back in 1995 that Clark and Darden planned on getting married, Clark instantly squashed the rumor, saying, "No, that's completely false. God knows where that one got started."

During ET's most recent sit-down with Clark just last week, the 62-year-old revealed that as of today, she and Darden are not in communication with one another. "We were in touch periodically after the trial for years," she said. "We ran into each other at times, and got to talk and reminisce, if you will."

"But we've gone separate ways, and we haven't spoken in quite some time now,” Clark added.

When ET reached out to Darden for a comment, the former prosecutor responded bluntly to any and all Simpson-related reports. "I have retired from life and bulls**t. You can quote me on that," he said.

The People v. O.J. Simpson: American Crime Story airs Tuesdays at 10 p.m. ET/PT on FX.
